reactantX and productX prefixes not handled correctly

[johannespostler]

The documentation [1] states that all kinds of prefixes reactantX where X is alphanumerical must be handled by the NodeSoftware. This is not the case as of now. IDEADB (and plenty of others) produce an error when working on the query [2]

select * where (product0.MoleculeStoichiometricFormula = 'O')

whereas [3]

select * where (product1.MoleculeStoichiometricFormula = 'O')

works fine (in my dictionary.py everything is defined with product1/2. I don't fully understand the documentation in this case. Is it meant to deal with X just do group reactions? Does it make sense to run queries like the following?

select * where (product5.MoleculeStoichiometricFormula = 'O')

Why not define a starting point (e.g. 0 or 1) for those reactant counters?
